Clamping elements

Due to the hydraulic working method, the ETP principle provides a number of important advantages for the customer: compact design, quick assembly, easy to position, good rotation, does not damage the contact surfaces and is easy to dismantle.

 

These qualities are important today and will become even more important in the future. Increased requirements for smaller installation dimensions, better rotation/balance at increased machine speeds, shorter downtime for service and increased precision means that more and more people are building in ETP hydraulic axle-hub connections.

ETP EXPRESS

ETP-EXPRESS has only one screw for pressurization, it is therefore particularly suitable where adjustments of the hub must be made quickly and accurately.


The screw is tightened radially, this allows no space to be taken up along the axis for mounting tools. Other components may be on the shaft right up to the flange.

 

ETP-EXPRESS has extremely small installation dimensions.

ETP-EXPRESS R

ETP-EXPRESS R manufactured in stainless steel SS 32 21 for really demanding environments. The pressurizing screw is coated with silver for low and even friction in the threads.

ETP-TECHNO

ETP-TECHNO is especially suitable for applications where quick frequent changes or adjustments with high precision are needed, can be assembled/disassembled 1000s of times.

 

It is easy to install even in tight spaces and has extremely good circular motion.

 

ETP-TECHNO is the high-precision connection among the ETP axle-hub connections.

 

classic

ETP CLASSIC

ETP-CLASSIC consists of a double-walled sleeve of hardened steel filled with a specially adapted pressure medium, sealing ring, piston, pressure ring and clamping screws.

ETP-CLASSIC R

ETP-CLASSIC R is a stainless variant of ETP-CLASSIC.

 

All parts are made of stainless hardenable steel. The stainless steel screws are silver plated for lower friction and with an external hex head for easy cleaning.

 

Properties, structure and function are the same as for ETP-CLASSIC.

ETP-MINI INCL. TYPE R

ETP-MINI is a good alternative to wedge joints or stop screws when a backlash-free joint with adjustment possibilities is desired. Typical areas of use are mounting hubs on small electric motors, stepper motors and encoders.

 

Because no keyway is needed, the axle is not weakened and the imbalance is reduced. This is especially important at high revs as the motor's bearings are sensitive to vibrations. Also available in stainless steel, ETP-MINI type R, especially suitable in e.g. the food industry.
